Amazon CEO reportedly raised Anthropic model concerns before government crackdown

Amazon CEO Andy Jassy raised concerns about Claude Fable 5 and Mythos 5 models being used for cyberattacks. The U.S. government banned worldwide access to both models after Amazon shared security risks with Treasury Secretary Scott Bessent. Anthropic CEO Dario Amodei refused to fix a jailbreak issue cited by former AI czar David Sacks.
